Description
LÜFTUNGSGITTER VENTILATION GRILLE
Die Erfindung betrifft ein Lüftungsgitter mit einem von Seitenwänden gebildetem Gehäuse, welches eine Öffnung umschließt, in die Lamellen eingesetzt sind, und eine mit einem Schlitzschieber belegte Rückwand mit Schlitzen besitzt .The invention relates to a ventilation grille with a housing formed by side walls, which encloses an opening into which the slats are inserted, and has a rear wall with slots which is occupied by a slider.
Derartige Lüftungsgitter sind in vielfältiger Form und Ausführung bekannt und in der DE-OS 39 07 559 beschrieben. Sie dienen der Führung von Zu- und Abluft bei Klimanlagen und weisen frontseitig waagrechte oder senkrechte, tropfenförmige Lamellen auf. Sie können aus Metall oder Kunststoff sein und vielfältigen Anwendungszwecken dienen.Such ventilation grilles are known in various forms and designs and described in DE-OS 39 07 559. They are used to guide the supply and exhaust air in air conditioning systems and have horizontal or vertical, teardrop-shaped slats on the front. They can be made of metal or plastic and serve a variety of applications.
Als nachteilig hat sich erwiesen, daß vor dem Lackieren desA disadvantage has been found that before painting the
Lüftungsgitters der Schlitzschieber bereits in dem Gehäuse montiert ist. Beim Lackieren setzen sich die Bleche durch das Pulver oder den Lack aneinander fest und können nach
dem Lackiervorgang nicht mehr ohne weiteres betätigt werden.Ventilation grille the slider is already mounted in the housing. When painting, the sheets adhere to one another through the powder or the paint and can re-form the painting process can no longer be operated easily.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Verschieben des Schlitzschiebers nach der Montage und dem Lackiervorgang sowohl in technischer als auch funktionaler Sicht zu verbessern.The present invention has for its object to improve the displacement of the slit slide after assembly and the painting process in both a technical and functional point of view.
Zur Lösung dieser Aufgabe führt, daß die Rückwand und/oder zumindest eine Seitenwand des Gehäuses mit zumindest einem Vorsprung versehen ist/sind.To achieve this object, the rear wall and / or at least one side wall of the housing is / are provided with at least one projection.
Durch diese in die Rückwand und/oder in die Seitenwand eingebrachten Vorsprünge entsteht ein genau definierter Abstand, der dazu dient, einerseits Klappergeräusche zu vermeiden und andererseits ein Verkleben durch den Lackiervorgang zu vermeiden.These projections, which are introduced into the rear wall and / or into the side wall, create a precisely defined distance which serves on the one hand to avoid rattling noises and on the other hand to avoid sticking due to the painting process.
Bevorzugt werden die Vorsprünge in einem Arbeitsgang zusammen mit der Herstellung des Gehäuses eingeformt. Das Gehäuse ist bevorzugt einstückig ausgebildet, wodurch Schweißarbeiten vermieden werden, was der Umwelt zugute kommt.
The projections are preferably formed in one operation together with the manufacture of the housing. The housing is preferably formed in one piece, whereby welding work is avoided, which benefits the environment.
eitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt inFurther advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
Figur 1 eine Frontansicht eines erfindungsgemäßen Lüftungs- gitters;Figure 1 is a front view of a ventilation grille according to the invention;
Figur 2 einen teilweise dargestellen Längsschnitt durch das Lüftungsgitter gemäß Figur 1 entlang der Linie II-II;Figure 2 is a partially illustrated longitudinal section through the ventilation grille according to Figure 1 along the line II-II;
Figur 3 einen Querschnitt durch das Lüftungsgitter gemäß Figur 1 entlang der Linie III-III;3 shows a cross section through the ventilation grille according to Figure 1 along the line III-III;
Figur 4 einen vergrößerten Ausschnitt des in Figur 3 einge¬ kreisten und mit X bezifferten Ausschnitts.FIG. 4 shows an enlarged section of the section encircled in FIG. 3 and numbered X.
Ein erfindungsgemässes Lüftungsgitter R besteht gemäß Figur 1 aus einem Gehäuse 1, welches eine frontwärtige Öffnung 2 ausbildet. Dieses Gehäuse 1 ist aus einem Materialstreifen hergestellt . Es besitzt eine in Figur 2 deutlich erkennbare Rückwand 3, in welcher Schlitze 4 eingestanzt sind.According to FIG. 1, a ventilation grille R according to the invention consists of a housing 1 which forms an opening 2 at the front. This housing 1 is made from a strip of material. It has a rear wall 3 which is clearly recognizable in FIG. 2 and in which slots 4 are stamped.
Von der Rückwand 3 sind Seitenwände 5 und 6 abgekantet, welche eine eigentliche Gehäusebox ausbilden.Side walls 5 and 6 are bent from the rear wall 3 and form an actual housing box.
Von jeder Seitewand 5 kragt ein Randsteifen 7 bzw. 8 ab, welche sich in den Eckpunkten überlappen und dort mittels Nieten 9 miteinander verbunden sind. Diese Lochnieten 9 in den Nietenpunkten dienen gleichfalls zur Befestigung des Lüftungsgitters R, beispielsweise an einem Blechkanal einer Klimaanlage od. dgl..An edge stiffener 7 or 8 protrudes from each side wall 5, which overlap in the corner points and is connected to one another there by rivets 9. These rivets 9 in the rivet points also serve to fasten the ventilation grille R, for example on a sheet metal duct of an air conditioning system or the like.
Durch die Öffnung 2 hindurch ist auf der Rückwand 3 ein Schlitzschieber 10 aufgelegt, bei welchem ebenfalls durchA slot slider 10 is placed on the rear wall 3 through the opening 2, through which also
Ausstanzungen Schlitze 11 gebildet sind, welche im wesentlichen mit den Schlitzen 4 der Rückwand 3
übereinstimmen. Die Stanzung der Schlitze 11 erfolgt entlang von drei umlaufenden Seiten des Schlitzes 11, so daß ein ausgestanzter Flügel 12 abgebogen werden kann. Hierdurch wird unter anderem eine Wirbelbildung innerhalb des Gehäuses 1 bzw. der eigentlichen Gehäusebox vermieden.Punched-out slots 11 are formed, which essentially correspond to the slots 4 of the rear wall 3 to match. The slots 11 are punched along three circumferential sides of the slot 11, so that a punched-out wing 12 can be bent. This avoids, among other things, eddy formation within the housing 1 or the actual housing box.
Nach oben und nach unten hin sind von dem Schlitzschieber 10 noch Führungsstreifen 13 und 14 abgekantet. Diese Führungsstreifen 13 bzw. 14 werden teilweise von Klammerstreifen 15 übergriffen, welche eine obere und untere Seitenwand 16 bzw. 16a durchsetzen, wie dies in Figur 2 und 3 dargestellt ist. Die Klammerstreifen 15 sind so angeordnet, daß ein Verschieben des Schlitzschiebers 10 entlang der Rückwand 3 freigegeben ist, so daß die Schlitze 4 ganz oder teilweise geöffnet bzw. geschlossen werden können.Guide strips 13 and 14 are also bent upward and downward from the slit slide 10. These guide strips 13 and 14 are partially overlapped by clamp strips 15 which pass through an upper and lower side wall 16 and 16a, as shown in FIGS. 2 and 3. The clip strips 15 are arranged in such a way that a displacement of the slit slide 10 along the rear wall 3 is released, so that the slits 4 can be opened or closed in whole or in part.
In der Öffnung 2 des Gehäuses 1 sind waagrechte Lamellen 17 eingesetzt und um eine Achse 18 drehbar. Selbstverständlich können anstelle von waagrechten Lamellen auch senkrechteHorizontal slats 17 are inserted in the opening 2 of the housing 1 and can be rotated about an axis 18. Of course, vertical slats can also be used instead of horizontal slats
Lamellen vorgesehen sein. Bevorzugt ist jede Lamelle 17 für sich um ihre Achse 18 bewegbar.Slats may be provided. Each lamella 17 is preferably movable about its axis 18.
Ferner ist insbesondere in Figur 4 erkennbar, daß die Rückwand 3 und die Seitenwand 16 mit Vorsprüngen 19, 20 versehen sind, die zu dem Schlitzschieber 10 Berührungspunkte 21 bilden. Somit wird zwischen dem Schlitzschieber 10 und der Rückwand 3 bzw. der Seitenwand 16 durch die Vorsprünge 19, 20 ein Spalt a gebildet. Bevorzugt sind diese Vorsprünge 19, 20 so angeordnet, daß sie einerseits als Abstandshalter das Hin- und Herschieben des Schlitzschiebers 10 erleichtern und andererseits einen reibungslosen Lackiervorgang möglich machen.
Furthermore, it can be seen in particular in FIG. 4 that the rear wall 3 and the side wall 16 are provided with projections 19, 20 which form points of contact 21 with the slot slide. A gap a is thus formed between the slit slide 10 and the rear wall 3 or the side wall 16 by the projections 19, 20. These projections 19, 20 are preferably arranged in such a way that, on the one hand, as a spacer, they make it easier to slide the slider 10 back and forth and, on the other hand, make a smooth painting process possible.
